Hi I found an old HDD (I think it crashed back in the day) and thought I'd give it a try and maybe recover some old files I had there; so I disconnected the current HDD and replaced it with the old one. But of course it didn't work, got a "BOOTMGR is missing" during boot up. Then I tried another old HHD that I knew had worked before but I got the same "BOOTMGR is missing" error. But now when I connected the original HDD again, the PC won't boot up anymore. I get this weird boot up screen that I've never seen before (sorry for the crappy huge picture but I hope this will do)- http://i18.photobucket.com/albums/b113/Orpheus666/P7150025_zps98c7193d.jpg There used to be a lot of some kind of lines of text that ran down but now there's only this box. I have no idea what to do. Any advice is welcome! EDIT: Forgot to mention I can't access BIOS because I only get a black screen with a blinking underscore sign when I try to do so.
Probably the boot order changed in the BIOS when you removed the only bootable HDD Check to make sure the working HDD is set as primary boot device EDIT - Check that the SATA cables are connected properly too, looks like it can't even see the HDD
I checked the cables, everything looks OK and connected properly. I also did the CMOS reset but it didn't chance anything, I can't get into BIOS, I get a black screen with a blinking underscore like before
Remove the HDD and see if you can get into the BIOS Chances it is still scanning hardware and hanging on the HDD
You were right, removing the HDD fixed the problem. I got into BIOS and everything is working again! Thank you Extraordinary and everyone else who took the time to reply, I really appreciate it!
